1. Cz 24 Pistol Serial Numbers

HISTORY OF THE CZ50 The CZ50 was designed immediately following World War II by brothers Jan and Jaroslav Kratchovil and intended as a military and police sidearm. Initially designated as the Model 006 during development, it was designated the Vzor 50 for its first-year production date after acceptance. It was widely used as a police Czech Police firearm, but it's military place was assigned to the more powerful CZ52. It is a 7.65mm (.32cal) double-action semiautomatic pistol with a profile very similar to the Walther PP. The magazine holds 8 rounds. The pistol is approximately 6.7-inches long with a barrel length of approximately 3.75-inches. Overall empty weight is 24 ounces.

The CZ50 was actually produced from 1950-1970 with a brief break in production from 1952-1957. The Czeska Zbrojovka armory at Strakonice was the initial production site for the the CZ50. CZ ceased production of the CZ50 and began concentrating on production of the CZ52 for the military between 1952-1954.

Cz 24 Pistol Serial Numbers

CZ - Strakonice ceased all production of pistols in 1955. Approximately 90,000 CZ50s were produced at Strakonice between 1950 and 1952 with serial numbers ranging from 650001 to about 740000.

Interestingly, the first CZ50 (sn 650001) was numbered to succeed the last CZ27 (sn 650000). In 1955, all production of pistols for the Czechs moved to the Presne Strojirenstvi factory at Uhersky Brod where CZ50 production restarted in 1957. It is unknown how many were produced by Presne Strojirenstvi after 1955, as there does not appear to have been a single coherent system of assigning serial numbers.

Pistols produced by Presne Strojirenstvi will generally have a five digit numeric and alpha combination for the serial number. The placement of the alpha characters changes location within the serial number from time to time and no determination has been made as to what system was being used or how many post-1957 pistols were produced. Early production CZ50s will have 6-digit serial numbers.

They will also bear the manufacture marks CESKA ZBROJOVKA on the top line and a lower line of NAR. PODNIK STRAKONICE on the left slide (llustration at right). Later production Strakonice pistols may also be marked in a single line with CESKA ZBROJOVKA - PRAHA while post 1957s manufactured at Uhersky Brod will have a 5-digit serial numbers (possibly mixed alpha-numeric) and will be marked VZOR 50 CAL 7.65 and MADE IN CZECHOSLOVAKIA on the left slide.

While the CZ50 was produced both for commercial and government use, pistols purchased by the Czech Ministry of the Interior will bear a crossed-sword proof mark and a two-digit number denoting the year of acceptance by the agency. The vast majority of early CZ50s went for Czech police use. In 1970, several modifications (mainly cosmetic) were made to the CZ50 and it was re-designated as the CZ70 for strictly commercial sale. The rugged blue police pistol known as the CZ50 faded into history but lived on as the CZ70, available in several finishes. Other than various finishes, the modifications made to create the CZ70 were minor and a blued CZ70 is almost indistinguishable from a CZ50. The CZ50/70 line was ceased production in 1982 and was replaced by the CZ82.

The 9mm Parabellum CZ82 actually served to replace the CZ50 in police use and the CZ52 in military use. Source: www.geocities.com/kirbytheog/czech.html. If it will feed them, why not keep HP's all the way through? Increased penetration, particularly important in small calibers. The.32 doesn't penetrate particularly well. They sometimes just bounce off of objects - like sternums and heads.

Remember that HP rounds flare to increase their wound channel size at the expense of penetration. You can afford that in a more powerful round, like a.40 S&W. I load my.380 Auto P-3AT that way. The first round is a warning, so to speak. If that doesn't stop them, the rest are to try to kill the SOB.

A few years back, when the surplus CZ 50's were cheap, I purchased one at a gun show in Phoenix because I felt the markings were a bit out of the ordinary. It is marked on the left side of the slide as follows: CZ trademark within a circle 'CESKA ZBROJOVKA-PRAHA' 7,65 within a circle On the left side of the frame is also a factory applied: 'MADE IN CZECHOSLOVAKIA' On the front gripstrap are the markings: 'NB 52' Finish is more of a bluish-grey rust type blue, and not salts blued. Virtually all the CZ 50's I have seen (and owned) were marked with the Strakonice logo.

Any thoughts on this one? Yours was a later Model made in 52. Vz 50s were produced initially at Strakonice and later at Uhersky Brod. Seems most imp.

Were the earlier versions, really dont think there is anything Special about it! Pistols manufactured at Uhersky Brod have 5 digit serial numbers preceded by a letter (which can change in the middle of a serial number series). Many Vz 50s bear the crossed sword government property stamp.

But the Majority of the CZ 50's & Cz 70's are very unreliable if US made Ammo is used, due to Euro Ammo having a wider Rim! Forgot to mention the serial number. There are no other original markings other than what I described and the serial number. Also, unless the slide logo was just a proprietary mark, Uhersky Brod is quite a ways from Prague ('Praha') And I suspect that 'Made in Czechoslovakia' is an export mark. It is not an 'import' mark, and it was very obviously applied at the works. On the right side of the frame is a barely visible CAI import stamp.) Last edited by dondone; at 01:14 AM.

Serial numbers start at 650001, continuing from the discontinued serial number range. Pistols manufactured at the Strakonice factory end in the 740000 range. You do know the Czech were not happy with the CZ-50 and thus the CZ-70 came about! Also than they were happy with that one either, but it was deemed more reliable than the CZ -50! Many of both types show up in Mint for $210.Hmmmm. This just seems to compound the issue, then. This pistol is in the 726000 range and is not a Strakonice marked pistol, which seems to be a bit of a distance from Prague as well.

Again, could the slide logo just be a proprietary mark used for export pistols in the 50's? Regarding the CZ 50 vs. The CZ 70, wasn't the 70 essentially identical with the 50 except for markings and a few cosmetic changes? There are Marking on many guns which we will never figure out! The Dot's theory on the CZ-52???????????????????????????????????

Actually the CZ 50 was dangerously unreliable! The CZ-50 is a double-action-only weapon; it cannot be fired in the single –action mode, where the hammer is cocked before drawing the trigger. Unfortunately, the CZ-50’s safety tends to slip internally, making the weapon sometimes safe when it is set on fire and unsafe when set on safe.

In addition, the CZ-50 is made of inferior materials and trigger draw can be creepy. The Czech Army solidly rejected this design in favor of the CZ-52, and today it is only found in the hands of police and security forces. The CZ-70 is a newer version, built of newer materials and addressing the reliability problems of the CZ-70. It replaced the CZ-50, but production ceased in 1983. Also the CZ-70 has a better Mag design, even they can be interchanged and also holds the slide open, Which the CZ-50 did not unless the CZ-70 mag was in use,so there were internal changes as well! I also have a Mint CZ-70 and with US Ammo, is a Jam-o-matic!

Never heard of CZ-50's being converted into CZ-70's! Last edited by vz58kid; at 02:29 AM. I once saw a CZ70 without an import mark. Are they all like that? I have very limited knowledge about these pistols.All guns as of 1968 were required to have import marks, at first sometimes they were tiny and in some cases even under the grip panels! Also some guns were allowed to be imported by 1 person and these were not required to be import marked, due to special BATF paperwork, but these guns were never allowed to be sold to anybody except the person who originally got permission! Also could have been smuggled or brought in to the US from Europe, used to be very EASY in the 60's.

In 68 also Full-Auto Guns which were manufactured outside of US were Banned from Import! The logo was used on Strakonice and Uhersky Brod pistols too, is means only the Directorate was in Prague, same as on Vz.27 pistols and other. The NB 52 means it was accepted by Police in 1952. The pistol should be normal SA/DA trigger system, when the SA dont fuctione You have a dammaged trigger bar or hammer nut? Best regards,Andy Vz.50 was never destined for Army as 7,65 was declared too weak for ArmyAndyB, thanks for that info. The one thing that would still puzzle me is why is it marked 'MADE IN CZECHOSLOVAKIA' if it were meant to be a police gun?

The marking is definitely factory applied, and in English. The obligatory 'import' mark is on the other side of the frame. ) Last edited by dondone; at 03:24 AM. Are we talking about the same weapon? All of my CZ 50's are double AND single action, the safeties all function reliably and they have all been perfectly reliable regardless of the brand of ammo I put through them.Yes, we are talking about the same gun, on some of the early 50's when the safety slipped, the gun would operate in the D/A Mode only! Also the later model would hold the slide open, original 50 Mags are very rare, seems the 50's all were imported with new 70's mags. NB was an armed force, organized and trained as such, but equipped to perform police rather than military functions.

For whatever reason, only early 1950's vz. 50 pistols are NB-marked. The 50 denotes 1950; NB51 and NB52 markings have also been seen. Some Differences between the CZ vz. 50 and the CZ vz. 70 include: Slide: The 50 has a shorter serrated region on the slide comprised of 14 serrations, whereas the 70 has 16 serrations spread out more widely.

Grips: 50 has brown, lined grips, whereas the 70 has black checkered. Takedown button: The 50 is serrated, whereas the 70 is checkered. Trigger: The 50 is smooth, whereas the 70 is serrated. Hammer: The 50 is solid, whereas the 70 has a hole to reduce weight. Magazine: Different floorplate, contour and color. Safety switch: There are subtle difference between the contours and lengths of the safety switch between the two models, internally as well as external!

Have you ever heard of the De-Cocker problems (alledged) in some CZ 52 Models? I have 4, one of which was refurbed last in 97 for the 4th time, all 4 of mine function 100% with the De-cocker Safety! Originally, the CZ52 was a DA/SA pistol as well, in 9mm! It was changed to SA when approved for service.

The Made in Czechoslovakia was stamped on various pistols made in this state and probably destined for export, as this pistol was too stamped with NB52 i believe there was a priority to equip police forces. Best regards,Andy PS to SNB problematic, certainly it was a force that was builded primarily for CS communist party to held the communist system, but it was under Ministry of Interior, so inside of it was a normal police as no other police units existed in early 50ies, the gendarmery was moved into SNB too in late 40ies. But it could be not compared to kasernierte VoPo typical for GDR. Last edited by AndyB; at 11:53 AM. I don't guess you still have access to that gun, but, in the case of the CZ 50's and 70's, the CAI import marks (and possibly others) were VERY lightly stamped and, in many cases, incompletely stamped on some of the guns, making them very easy to overlook. It's in the safe downstairs.

It was made in 1981 and has no import stamp anywhere. I detail stripped it.no mark. I don't even remember when or where I aquired it but it was from an individual some years ago. I just thought they were all like that. Jardows' i read about some probs you had on the CZ Forum! Beautiful south - blue is the colour rar. Both types of ammo you listed are Euro not US and thus work fine, the prob with yours only working in D/A, was quite common with the un-reliable safety in the 50 model!

Which could work opposite as meant and if it slipped internally could cause it to be dangerous. Why do you think they changed it internally? Surely it would not make sense to simply change the Grips,mag and grooves on the slide and only change the Safety to look different externally! So in your above statement, you basically gave credence to all i had said! They are nice guns, i never said the 50 was junk, but simply that the 70 was made out of better materials, mainly the steel, most dont know this. After i polished the feed ramp in my 70 it feeds all HP's fine!:D Just like many people had never heard to the also dangerous safety/de-cocker on the 52, but not 1 of my 4 ever had a prob. The 52 alsways has and will be my favorite milsurp, and i think 99% of the alledged 52 probs were caused by BUBBA putting in the dangerous type Firing Pin which will by-pass the safety and reduce the alledged Trigger Slap!

Then the next owner will have a A/D! Even on the 52 a lot is not or will never be known, in my opinion the 1-4 dot theory or even No dot, does represent accuracy, but the Czech's never answered that!

Since if acknowledged nobody would buy any but 1 dot, and somehow later on for various reasons unbeknown, i believe the Czech' actually added a few more dots on some 52's to actually discredit the accuracy Theory, so all types would sell! And it is exceptional accurate.:cool: but i was told that dots are how many factory rebuilds happen to the gun!:cool: all the ones ive owned had a few dots the 4Th one i owned had 6 dots and was more accurate then the other 3 prior with same ammo less dots. This one dot gun out shot it, and had a better finish. I thought it was because it was tighter, less rebuilds. I still think its more logical to keep up with how many rebuilds with the dots to account for frame / slides ware, and over all metal stress.:cool: just think if a barrel that was not accurate, worn got replaced with a new barrel and and became very accurate how would you fix all the dots saying it wasn't.

As Andy as stated 'Made in Czechoslovakia' stamping means that run was destined for export, although Czech's took what they needed for armanent runs. It's not an import mark though. I've never heard the myths about the 50's being a bad gun, nor has their been an citations. The model 70's are essentially the same pistol as has been stated with some 'minor' differences.

With ammo feed problems, you take any used mil surp pistol, run enough milsurp/commercial ammo though it, you are bound to find one that your pistol doesn't like. Only problems ever experienced is jam with US made ammo when mag is full, works fine if load with 6 rounds. Both work fine with Euro ammo (S&B) as previously mentioned.

NB50 stamped on both. One nice blu job and the other with a blu frame and almost plum brown slide. Serial number on slide and frame match on both. Safety's function fine. Bought for $99 each 4-5 years ago.

One up - one down for extra home protection (two story house). Not my only home protection, just extra sitting up high out of reach of grandkids. Like my 9X18MM Mak better though.
